F. For stock thicker than 1", you may wish
to use double biscuits at each location.
Set the height adjustment to allow at
least 3/16" of stock between the biscuit
and the edge of the work surface. Make
all cuts at this fence setting before
readjusting the fence for the lower cuts.
Again, there should be at least 3/16" of
stock between the biscuit and the
outside wall and between the biscuits
themselves (see Figure 17).

2. FRAME JOINTS
Frame joints are an ideal application for
biscuit joinery. With the plate joiner you
can create a very strong, precise joint that
is much faster to make than a dowel or
mortise and tenon joint. Figure 18 shows
two types of frame joints. Follow the steps
outlined below.
A. Arrange the workpieces on a flat work
surface exactly as they are to be
assembled.
B. Select the proper biscuit size based on
the length of the joint. If the frame
pieces are too narrow for a #0 biscuit,
you will have to allow the biscuit tip to
protrude slightly. Then trim the tip off
after the joint is dry (see Figure 12).
C. Lay out the biscuit locations.
D. Set up the tool by selecting the depth
that corresponds to the chosen biscuit
size. Lock the fence at 90 ° and adjust
the fence height to centre the biscuit on
the stock thickness.

E. Clamp the workpiece and position the
Plate Joiner to make the first cut (see
Figure 19).
F. Turn on the tool and make the plunge
cut.
G. Repeat for each layout mark.
H. Glue, assemble and clamp the frame.

3. CORNER JOINTS (SEE FIGURE 20)
Corner joints are another common and
excellent application for biscuit joinery.
Follow the procedure below.
A. Arrange the workpieces exactly as they
are to be joined.
B. Select the biscuit size and layout the
biscuit locations.
